Hi Farming Friends! Let's talk about the little villain of rice leaf curlers today. This insect is cunning, picking on the young leaves of rice. They roll up the leaves, hide in them and eat them, and gnaw the good leaves into a mess.
The leaves of the rice are tossed by them like this, photosynthesis is affected, the rice does not grow well, the rice ears are few and deflated, and our harvest can be greatly reduced. Moreover, this leaf curler insect reproduces very quickly, and if you are not careful, you can cause a catastrophe.
The "doorway" of pesticide selection
So what kind of pesticide can be used to cure this leaf curl? There's a lot of attention to in this.
1. Efficient and safe: We have to find pesticides that have a particularly good effect and will not cause much harm to rice and the environment. This can not only kill the insects, but also ensure that our rice is green and healthy.
2. Specialize in leaf rollers: Choose a medicine that specifically targets leaf rollers, just like a tailor-made mantra for it, and it will work as soon as you use it.
3. Environmental protection does not cause trouble: You can't harm other small animals in the rice field because of insects, otherwise the ecology will be messed up, and there will be more trouble in the future.
4. Affordable and easy to use: On the premise of solving the problem, we also have to consider the wallet and choose the kind of cost-effective pesticides.
Recommended for easy pesticides
Come, I would like to recommend a few good medicines to deal with leaf rollers.
1. Biopesticides: like emamectin benzoate · indoxacarb, which is a master of biopesticides. It works particularly well on the larvae of leaf rollers, and is environmentally friendly, so it is safe to use.
2. Chemical pesticides: If the leaf curlers are too fierce, you can invite avermectin and chlorantraniliprole. They are powerful and can quickly subdue leaf curlers.
Correct "posture" for using pesticides
If you have good medicine, you have to be able to use it.
1. Look for the right time: You have to find out when the leaf curlers appear a lot, and use them when they are still young, the best effect.
2. Accurate dispensing: According to the instructions, the amount of medicine is registered, more waste, less useless.
3. Spray carefully: When spraying, you should be thorough, and the front and back of the leaves, especially the places where they are rolled, must be sprayed.
4. Change the dressing wheel: Don't always use one medicine, otherwise the leaf rollers will have resistance, and the medicine will not work.
Comprehensive prevention and control "combination punch"
It is not enough to rely on pesticides alone, we also have to play a set of "combination punches" of comprehensive prevention and control.
1. Agricultural control: Usually manage the paddy fields well, and get the right water and fertilizer, so that the rice grows strong, and the leaf rollers will not love it.
2. Physical control: hang a few insecticidal lamps to attract the adult leaf rollers to eliminate them at night.
3. Biological control: Protect the beneficial insects in the rice field, such as red-eyed bees, and let them help us deal with leaf rollers.
In short, if we want to defeat the rice leaf curler, choose the right pesticides, use the right methods, and add comprehensive control, our rice can thrive and a bumper harvest is in sight!
I hope everyone can drive away the leaf curls and harvest a full harvest of rice!
